It's difficult to say what the problem is without a sample test plan,
because it depends exactly where the functions are placed.
Have you tried adding some Debug Samplers to the plan to show the values?
That might help pin things down.
Can you create a Bugzilla issue and attach the JMX file?
Redact any private info first - but make sure the plan still fails!
Or send me a copy of the JMX file privately?
Please do not send it to the list.
